What are some options available for a madsonic client on various devices? My use case is that I would like to install a client on my roku, amazon fire TV, or raspberry pi to play music from my madsonic server. I could always just use my phone to cast to my chromecast Audio, but I want to be able to use my harmony remote to skip songs, which is why I'd like to use one of those devices. Needs to be easy enough to navigate for my technologically challenged children.
